Audix f50 Dynamic Vocal Microphone

Overview

The f50 is a dynamic vocal microphone designed for a wide variety of live and studio applications. It is known for its warm, natural sound reproduction, resistance to feedback, and ability to handle high sound pressure levels without distortion. The f50 features a unidirectional and uniformly controlled cardioid polar pattern, which helps to isolate vocals from other instruments on stage. It has a wide frequency range of 50 Hz - 16 kHz. An optional noiseless, magnetic on-off switch is available with the f50S model. The f50 is designed to sound clear and full-bodied on small to mid-size PA systems. It is well-balanced, comfortable to hold, durable, and manufactured with high standards and tight tolerances. Roadworthy construction includes a precision cast zinc alloy body with a black e-coat finish, a steel mesh grill, and a gold-plated XLR connector.

Specifications

Dimensions

Diagram showing the dimensions of the f50 microphone: 169 mm length, 23.5 mm diameter at the base, and 53.5 mm diameter at the widest point of the grill.

Frequency Response

Graph illustrating the frequency response of the f50 microphone. The response is relatively flat from 50 Hz to approximately 2 kHz, with a gradual rise peaking between 2 kHz and 5 kHz, and then a gradual decline towards 16 kHz. The response is within a range of approximately -10 dBm to 0 dBm.

Polar Patterns

Two polar pattern graphs for the f50 microphone. The 'Lo' frequency graph shows a consistent cardioid pattern. The 'Hi' frequency graph also shows a cardioid pattern, with slightly more directivity at higher frequencies. Both patterns indicate rejection of sound from the rear (180 degrees).

Architect and Engineer Specifications

The microphone shall be of the dynamic type operating on the moving coil principle and the polar pattern of the microphone shall be cardioid. The nominal output impedance shall be equal to 250 ohms at 1 kHz. The microphone shall have a sensitivity of 1.8 mV / Pa at 1 kHz and a sound pressure level ≥138 dB. The microphone body shall be die cast zinc alloy and the grill shall be steel mesh. The overall dimensions shall be 23.5 mm in diameter at the base, 53.5 mm at the widest point on the grill, and 169 mm in length.

Operation and Maintenance

The f50 is a low impedance microphone and should be plugged into a "mic level" input on the console, mixer, or recording device. The microphone does not require phantom power, but it will not be affected if phantom power is running simultaneously. Avoid plugging or unplugging the microphone from a PA system unless the channel is muted or the system volume is turned down to prevent loud "popping" noises that could damage speakers. The f50 is manufactured to exacting specs with roadworthy construction. However, the capsule is highly sensitive and should be handled with care. Avoid extreme temperatures and store the microphone in the provided pouch when not in use. Moisture of any kind can adversely affect the sound and performance of the microphone.

User Tips

The f50 has a unidirectional (cardioid) pick-up pattern to help eliminate sound from other instruments on stage from "bleeding" into the microphone. Operating distance for vocal applications can vary between 2-6 inches depending on the number of instruments on stage, the volume of the music, and the type of monitors being used. When using floor monitors, position the microphone so that it is parallel to the floor. When using multiple microphones on a live performance stage, allow a distance of 2-3 feet between mics to avoid phase issues.
